Ansible Automation Quality Control & Assurance 4

Question 1

Which Ansible strategy minimizes the risk of rolling a bad change across all hosts simultaneously?

Accepted Answer

rolling_update with serial

Answer

Setting `serial` limits how many hosts are updated in each batch, so failures are detected and stopped before the change propagates to all hosts.

Question 2

What does `any_errors_fatal: true` do in an Ansible play?

Accepted Answer

Stops the entire play immediately when any host reports a failure

Answer

`any_errors_fatal: true` causes Ansible to abort the entire play across all hosts as soon as one host fails, preventing partial deployments.

Question 3

Which Testinfra function would you use in a Molecule verify test to confirm a package is installed?

Accepted Answer

host.package('nginx').is_installed

Answer

`host.package('nginx').is_installed` returns True if the named package is installed on the system under test.

Question 4

In Ansible, what is `changed_when: false` commonly used for?

Accepted Answer

To suppress change reporting for read-only or informational command tasks

Answer

`changed_when: false` prevents tasks like information-gathering shell commands from falsely reporting that they changed the system state.

Question 5

Which Ansible module is best suited for verifying that a configuration file contains an expected line after deployment?

Accepted Answer

assert with lookup('file')

Answer

Using `assert` with `lookup('file', ...)` and a string search lets you verify file content declaratively within a quality check task.
